Scott, here<http://www.flartoolkitdocs.org/FAQ/getting-the-screen-coordinates-of-a-marker> you will see how to get the screen coordinates out of the detector.
For each frame, you should try something like this: mask.graphics.clear(); var i:int, sq:FLARSquare = detector.getSquare (); mask.graphics.beginFill(0); mask.graphics.moveTo(sq.sqvertex[0].x, sq.sqvertex[0].y); mask.graphics.lineTo(sq.sqvertex[1].x, sq.sqvertex[1].y); mask.graphics.lineTo(sq.sqvertex[2].x, sq.sqvertex[2].y); mask.graphics.lineTo(sq.sqvertex[3].x, sq.sqvertex[3].y); mask.graphics.endFill(); that -could- do... but it's completely untested ! :) .. Also maybe you will have to determine if two points will determine a side of the rectangle or a diagonal! cheers Cauê 2010/2/3 Scott <[email protected]> > That would be great if I knew how to do that. :-) > > Could you give me a hint on where to start looking? > > > > On Feb 3, 3:03 pm, Cauê Waneck <[email protected]> wrote: > > Scott, wouldn't it be better to put a mask that changes according to FLAR > > points' position? > > > > 2010/2/3 Scott <[email protected]> > > > > > > > > > Apologies if this has been covered, but I'm not quite sure how to > > > phrase the question. > > > > > I'm trying to achieve an effect similar to this: > > > > >http://www.youtube.com/watch?v=TW6_X9qBeds > > > > > I have 5 planes arranged to give the appearance of a cube recessed > > > inside of an AR pattern.
